    example, the regexp r'(?P<abc>)(?P<abc>)' is not allowed, because a
    single name can't mean both "group 1" and "group 2" simultaneously.
!   Python 2.2 detects this error at regexp compilation time; previously,
!   the error went undetected, and results were unpredictable.

!   Python 2.2 detects this error at regexp compilation time;
!   previously, the error went undetected, and results were
!   unpredictable.  Also in sre, the pattern.split(), pattern.sub(), and
!   pattern.subn() methods have been rewritten in C.  Also, an
!   experimental function/method finditer() has been added, which works
!   like findall() but returns an iterator.

    unless you have a masochistic desire to port your code to RISCOS.
  
+ - mimetypes.py has optional support for non-standard, but commonly
+   found types.  guess_type() and guess_extension() now accept an
+   optional `strict' flag, defaulting to true, which controls whether
+   recognize non-standard types or not.  A few non-standard types we
+   know about have been added.  Also, when run as a script, there are
+   new -l and -e options.
+ 
+ - statcache is now deprecated.
+ 
+ - email.Utils.formatdate() now produces the preferred RFC 2822 style
+   dates with numeric timezones (it used to produce obsolete dates
+   hard coded to "GMT" timezone).  An optional `localtime' flag is
+   added to produce dates in the local timezone, with daylight savings
+   time properly taken into account.
+ 
+ - In pickle and cPickle, instead of masking errors in load() by
+   transforming them into SystemError, we let the original exception
+   propagate out.  Also, implement support for __safe_for_unpickling__
+   in pickle, as it already was supported in cPickle.

  Build
  
+ - The dbm module is built using libdb1 if available.  The bsddb module
+   is built with libdb3 if available.
+ 
+ - Misc/Makefile.pre.in has been removed by BDFL pronouncement.

    PySequence_Size().
  
+ - New argument unpacking function PyArg_UnpackTuple() added.
+ 
+ - New functions PyObject_CallFunctionObjArgs() and
+   PyObject_CallMethodObjArgs() have been added to make it more
+   convenient and efficient to call functions and methods from C.
+ 
+ - PyArg_ParseTupleAndKeywords() no longer masks errors, so it's
+   possible that this will propagate errors it didn't before.
+ 
+ - New function PyObject_CheckReadBuffer(), which returns true if its
+   argument supports the single-segment readable buffer interface.

  New platforms

+ 
+ - PythonScript has been moved to unsupported and is slated to be
+   removed completely in the next release.
+ 
+ - It should now be possible to build applets that work on both OS9 and
+   OSX.
+ 
+ - The core is now linked with CoreServices not Carbon; as a side
+   result, default 8bit encoding on OSX is now ASCII.
+ 
+ - Python should now build on OSX 10.1.1
